The present application claims the benefit of the provisional patent application Ser. No. 61/739,376, filed Dec. 19, 2012, which is incorporated herein by reference.The subject matter disclosed herein relates generally to non-woven matrices and, more particularly, to cotton shoddy and/or natural fiber matrices and systems and methods for producing cotton shoddy matrices.Commercially available technology exists today for the purpose of applying liquids to a non-woven matrix, such as a matrix constructed from natural fiber and/or cotton shoddy. One technology includes dipping a continuous feed of a non-woven matrix into a tank of emulsion resin, then squeezing the resin-saturated matrix to remove excess content, while a second technology includes converting emulsion resin into a dense foam using a foam generating system, and injecting the foam into the matrix under pressure using a specially designed application head made for this purpose. While both of these technologies may work to some degree for certain natural fiber non-woven matrices, neither is well suited to resin-saturate cotton shoddy.Several disadvantages exist with conventional foam injection ...

Moreover, the fiber-reinforced resin member has a simple structure in which merely the density of the axially right-angled fiber in its interior is changed, thereby minimizing any increase in the production cost.

A biofabricated material containing a network of crosslinked collagen fibrils is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability. It can have substantially identical grain, texture and other aesthetic properties on both sides distinct from natural leather where the grain increases from one side (e.g., distal surface) to the other (proximal inner layers). 1. A biofabricated material(i) comprising a network of non-human collagen fibrils,wherein less than 10% by weight of the collagen fibrils in the material are in the form of collagen fibers having a diameter of 5 μm or more, are in the form of fibrils aligned for 100 μm or more of their lengths, or both;wherein said material contains no more than 40% by weight water;wherein said material contains at least 1% of a lubricant; or(ii) comprising a network of recombinant non-human collagen fibrils, wherein the collagen contains substantially no 3-hydroxyproline;wherein said material contains no more than 25% by weight water;wherein said material contains at least 1% of a lubricant.215-.

Fire and Smoke Suppressing Surface for Substrates

Номер: US20150240412A1
Автор: Rowen John B.
Принадлежит:

This invention relates generally to fabrics, films, sheets and other supporting media that contain and transport fire retarding materials. These transport media deliver fire retarding and smoke suppressing constituents to the surface of fiber reinforced polymer (FRP) composite substrates during a manufacturing process. Upon exposure to open flame or radiant heat, the resultant manufactured product has much lower surface flammability and smoke development characteristics than would otherwise be achieved by the substrate material alone. By economizing the fire retardant constituents at the surface only, cost is reduced while also avoiding deleterious adulteration of the substrate material. When fire is prevented from penetrating the surface, combustion of the entire part is delayed or prevented. By embedding fire retardant within the surface using the native resin, no peeling or chipping occurs (as with paint), and the finish will be essentially as hard and durable as an untreated part. 1.
